SPECIFICATION Application filed October 26, 1901. Serial No. 80,066. (No model) To all whom it may concern.-

Be it known that I, HUDSON S. CLARK, a citizen of the United States, and a resident of Sigourney, in the county of Keokuk and State of Iowa, have made certain new and usefulImprovements in Pumps, of which the following is a specification.

My invention is an improvement in pumps, and'has for an obj ect'to provide a simple novel construction andarrangement of parts whereby to prevent the circulation of sand with the Water by the operation of the pump in drilled, driven, or other wells; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a vertical longitudinal section of my invention as in use, the pump tubes and the diaphragm being shown in elevation. Fig. 2 is a vertical 1ongitudinal section of the invention,showing the inlet ends of the pipes sloped instead of square, as in Fig. 1. Fig. 3 is atop plan view of the diaphragm. Fig. 4 is a cross-section of the diaphragm on about 1ine4 4 of Fig. 3. Fig. 5 is a sectional view of the diaphragm with the sections thereof slipped slightly apart, and Fig. 6 is a detail perspective view showing one of the sections of the diaphragm.

In the construction shown the pump-tube A is supported within the well-casing B and is provided at its lower end with the upwardlyprojecting inlet pipe or pipes 0, preferably two or more, whose upper ends at O and O are covered by suitable screens. The upper ends of the pipes C may be square, as shown at O in Fig. 1, or they may be sloped, as shown at O in Fig. 2. The pumping devices operating in connection with the tube A may be of any desired form to raise the water in the tube A, the water being supplied to such tube through the pipes O, as will be understood from Figs. 1 and 2. It will he noticed that the pipes C are diametrically opposite each other and that the water circulating upward and then down into the said pipes will cause currents which will oppose each other, and so aid in retarding any upward movement of the sand with the water. To further retard any upward circulation of the sand and to prevent it from passing upward to the inlet-openings of the inlet-pipes O, I provide a perforated diaphragm D, which fits around the pumptube A and inlet-pipes C and Within the easing of the well and forms a closure across the well below the inlet ends of the pipes C, which will operate to prevent the passage of the sand to the said inlet-openings. It will be noticed from Fig. 3 that the diaphragm D is provided with a central opening D for the pump-tube A and with side openings D to fit over the inlet-pipes C, so the diaphragm can fit over and around the said pipes and be adjusted to the position shown in Figs. 1 and 2. In order that the diaphragm may be readily slipped down in the casing to position for use, I make the openings D and D in separable plate-sections EE and connect such sections by bolts F, While to permit the passage of the diaphragm past any slight obstructionsin the casinglform such diaphragm with hinged sections G G, which have ahinged connection at their inner edges G with the central portion of the diaphragm, which is shown as composed of the platesE E, which with the hinged sections G, I provide springs p H, which extend over the upper side of the diaphragm, are heldin keepers h and h, and operate to press the hinged sections G normally downward and at the same time permit them to spring or yield upwardly to pass any obstruction in inserting the diaphragm down in the well-casing. The springs also permit the sections Gtoyield downwardly to.

pass any obstruction in withdrawing the diaphragm from the well. Thus the springs operate to hold the sections Gin place and per.-

mit them to yield in either direction, as may be desired. In thespecific construction shown the plates E and the sections G are provided at their adjacent edges with depending flanges e and g, which are secured together and are provided with openings for the passage of the.

bolts F, of which I preferably employ two, as shown in Figs. 1, 2, and'6.

By the described construction it will be seen the diaphragm can be readily assembled and applied for use and will operate when in use to reverse the current, and so prevent any active upward circulation of the water and will so prevent the upward movement of sand, as

well as stop any particles that may move upward with any slight circulation that may occur during the pumping operation.

The diaphragm may be of brass, galvanized iron, or other suitable material. In operation the diaphragm will operate as a regulator to steady the flow of Water to such an extent as to prevent the flow of sand or similar articles to the inlet-pipes O. 7

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The improvement in pumps herein described consisting of the pump-tube having the two upturned inlet-pipes arranged diametrically opposite each other and on opposite sides of the pump-tube, and the perforated diaphragm composed of the central portion consisting of the sections adjustable upon each other at their inner edges and recessed in said edgesformingthe openings tofitaround the pump-tube and inlet-pipes, means connecting said sections of the central portion, the. outer sections having a hinged connection with the central portion, and the springs extending between the central portion and the hinged sections and adapted to permit the yielding of the hinged section either up or down substantially as set forth.

2. In a pump a diaphragm perforated for the passage of the water and consisting of a central section having openings for the passage of the pump-tubes and spring-actuated sections hinged at their inner edges to the central portion substantially as set forth.

'3. The combination with the pump-tube and its inlet pipe or pipes and the casing, of the perforateddiaphragm fitted within the casing and around the pump-tube and inlet-pipe below the inlet-openings of the inlet-pipe substantially as set forth.

4. The combination with the pump-tube of a perforated diaphragm fitting around the same and having its outer sections yieldingly supported whereby they can pass obstructions within the well-casing substantially as set forth.

5. A diaphragm for use in Wells and provided with openings formed partially in opposite separable sections and means for connecting such sections and securing same upon the pump-tube substantially as set forth.

6. The combination of the central diaphragm portion composed of separable platesections recessed in their adjacent edges whereby to fit the pump-tubing, the outer sections hinged to the central portion, and the spring-plate extending transversely over or across the central and hinged portions substantially as set forth.

7. The combination of the pump-tube, its inlet-pipes, and the perforated diaphragm having its central portion separated into sections to fit on opposite sides of the pump-tube and inlet-pipes, and means for connecting said sections together substantially as set forth.

8. The combination with the pump-tube and its inlet-pipes, of a strainer-diaphragm fitting around the pump-tube and inlet-pipes below the inlet ends of the latter substantially as set forth.
